Title: Offset adjustment method for focus servo apparatus
Inventor: TSUKIHASHI AKIRA
IPC: G11B7/085
Filed: 1993-02-24
Abstract: PURPOSE:To realize automatic offset adjustment only with a focus servo circuit system by providing a feedback route of the offset adjusting system to a gain adjusting amplifier. CONSTITUTION:An FE signal sent from a focus error(FE) detecting circuit 1 is impressed to a non-inversion input terminal of a gain adjusting amplifier 5, while a PWM signal sent from a pulse width modulation(PWM) signal generating means 10 is impressed to an inverted input terminal. Therefore, when the period of '1' of the PWM signal is maintained longer, a DC voltage signal is subtracted from the FE signal output from an amplifier 5. On the contrary, when the period of '1' of the PWM signal becomes short, a DC element is increased. Therefore, the PWM signal having changed a duty ratio to correct the DC voltage element of the FE signal is input to the amplifier 5 through an LPF 11 and an adequate correction voltage corresponding to a reproducing signal is impressed. Thereby, the offset adjustment can always be conducted.

Title: Two-wire contactless switch
Inventor: NODERA HISATOSHI
IPC: H03K17/945
Filed: 1980-03-18
Abstract: PURPOSE:To reduce both a leakage current and residual voltage by flowing only the current that a sensor circuit requires at any time, by using a constant current circuit which performs constant-current operation even at a low voltage by using FET. CONSTITUTION:When the output of sensor part 51 is at H, transistor Tr3 is turned off, and Trs 2 and 1 are therefore both turned off to supply sensor part 51 with a current passed through constant current circuit 6, so that its voltage is stabilized by Zener diode ZD2. When the output of sensor part 51 is at L, Tr1-3 turns on. At this time, if the residual collector-emitter voltage of Tr1 is denoted as VA, voltage VC applied to sensor part 51 is the difference between VA and voltage VB dropping across circuit 6. This circuit 6 can have stable constant-current characteristics even in a low-voltage range by using FET1. Voltage VA, on the other hand, should be higher than the sum of voltage VC and the voltage that circuit 6 requires, but the voltage of circuit 6 can be made extremely low, so that voltage VA can be reduced extremely.

IPC: H01J23/34
Filed: 1982-03-09
Abstract: PURPOSE:To remove the difficulty in centering adjustment and the danger of breaking an expensive high power traveling wave tube while it is being replaced. CONSTITUTION:A collector power supply 2 supplies collector voltage Vck between the collector C and cathode K of a traveling wave tube 1 and a body power supply 3 supplies body voltage VBK between body B and cathode K of the traveling wave tube 1 in addition to the collector power supply. For centering adjustment, the collector C and the body B are substantially kept in the same potential and the collector C, the body B, and an anode A are substantially kept in the same potential by means of an anode voltage control circuit 4. Then the output voltage of the collector power supply 2 is applied to the traveling wave tube 1 by setting the output voltage to the lower value than the normal value by about 1 to 3kV as a whole although the output voltage may vary depending upon each traveling wave tube 1. As a result, the traveling wave tube 1 is operated as a diode. In this case, the output voltage of the collector power supply 2, i.e. VCK is set in the specified range and the oscillation due to a large flow of collector current IC does not occur. Besides, in this state, while the collector current IC and the body current IB are being read, centering adjustment is performed so that the body current IB can be minimized.
